Forces in a Three-Charge System p.21.2

Consider two point charges located on the x axis: one charge, = -18.5 , is located at = -1.650 ; the second charge,

= 37.5 , is at the origin .  

What is the net force exerted by these two charges on a third charge = 46.0 placed between and at = -1.100 ?

Your answer may be positive or negative, depending on the direction of the force.
